Abstract: Combinations of fixture assembly parts assembleable to provide fixtures to support and convert a small high speed electric grinder such as a "Dremel" brand tool into a lathe, a router, a circular saw blade sharpener or a shaper. All of the fixture parts are formed of simple sheet metal shapes and common screw machine hardware fittings such as bolts, nuts, washers and threaded rods. The sheet metal shapes are formed with simple holes and slots thus the parts for the fixture assemblies are very inexpensive to manufacture. The parts are also very simple to assemble and disassemble into the various configurations.
